Minor bugfixes,
Reorganized the index function of the Dashboard_Controller. It now redirects to the matching function. So we can create seperate views

Webshop_Model no longer returns, it sets its variable.

Added descriptions to explain what still needs to be done.
Reviewed the request dimmensions and metrics and changed these.

All we need Google Analytics for now is to define which order belongs to which marketingchannel.
Reviewed the requested metrics and dimensions. We only need to know orders per channel.

There is a value in metrics, because this is required, this value is not used however.
Updated the library.
Reviewed the code, made a small adjustment. The metrics getting parsed now adds the orders to an array where the marketingchannel name is the key.
When using the Cronjob_Controller we don't need the init function from the Main_Controller. I do not like this way, but I can't find something now.
And the implementation from the previous commit. -.-'
Since the constructor changed to an init function, I have no reason to call the contructor fo the main_controller.
Added a CronJob which fetches all data from Google Analytics and Magento webshos configured in the googleaccount/webshop table.

Multi user functionality is ALMOST here!
